I refer to the Incident: Vietnam A321 at Ho Chi Minh on May 6th 2012, runway excursion. I was the captain of the aircraft following the said aircraft involved in the incident. My aircraft was about 10 miles behind the Airbus. Passed through a moderate shower of rain about 7 miles from touchdown but in clear conditions by 1500'. Good visibility from then on with wind from about 210° at 10 kts. (as per METAR) Runway looked wet associate with recent heavy rain. Needless to say we were instructed to carry out a Go-around. Landed about 20 minutes later on RWY 25L.
